Rotationally-molded wall bunk

Abstract

In one aspect, a wall bunk is provided that includes a rotationally molded body having an overall length, a mounting portion of the body, and an elongate bed pan. The bed pan has a lower wall including a mattress support surface and a front wall. The lower wall includes curved wall portions at internal kiss-offs of the body. The mattress support surface has recesses defined at least in part by the curved wall portions for collecting moisture. The wall bunk further includes a rail configured to be connected to the front wall of the bed pan. With the rail connected to the front wall, the front wall has an uncovered portion with a length that is at least forty percent of the overall length of the body to provide a lateral opening for ingress and egress relative to the wall bunk.

What is claimed is: 
     
         1 . A wall bunk comprising: a rotationally molded elongate body, the body having an overall length; a mounting portion of the body; a bed pan of the body; a lower wall of the bed pan, the lower wall including a mattress support surface; curved wall portions of the lower wall at internal kiss-offs of the body; recesses in the mattress support surface defined at least in part by the curved wall portions for collecting moisture; a front wall of the bed pan; a rail configured to be connected to the front wall of the bed pan, the rail having a length and a height perpendicular to the height, wherein the length of the rail is less than four times the height of the rail; and an uncovered portion of the front wall of the bed pan with the rail connected to the front wall of the bed pan, the uncovered portion of the front wall having a length that is at least forty percent of the overall length of the body to provide a lateral opening for ingress and egress relative to the wall bunk; wherein the rail has at most three outer openings to be positioned on one side of the front wall and at most three inner openings to be positioned on an opposite side of the front wall, each one of the outer openings aligned with one of the inner openings to receive an anchor for extending through the front wall and connecting the rail to the body and wherein each of the recesses is circular and has a concave surface and a circular juncture between the concave surface and the mattress support surface, the circular juncture having a radius of curvature; and wherein the recesses each have a depth that is shorter than the radius of curvature of the circular juncture of the recess. 
     
     
         2 . The wall bunk of  claim 1  wherein the rail is rotationally molded and has an interior. 
     
     
         3 . The wall bunk of  claim 1  wherein the rail includes a channel configured to receive a rail mounting portion of the front wall of the bed pan. 
     
     
         4 . The wall bunk of  claim 1  wherein the recesses each have a recess length that extends along the length of the body and a recess width perpendicular to the recess length that is at least half of the recess length. 
     
     
         5 . The wall bunk of  claim 1  wherein the curved wall portion of each of the recesses curves inward from the mattress support surface with a radius of curvature; and
 wherein the recesses each have a depth that is shorter than the radius of curvature of the curved wall portion of the recess. 
 
     
     
         6 . The wall bunk of  claim 1  wherein the curved wall portions are each partially spherical. 
     
     
         7 . The wall bunk of  claim 1  wherein the bed pan has a central longitudinal axis;
 wherein the recesses include groups of recesses, wherein each group comprises a pair of recesses aligned with the central longitudinal axis and another recess laterally offset from the central longitudinal axis. 
 
     
     
         8 . The wall bunk of  claim 1  wherein the mounting portion of the body includes a rear wall of the bed pan;
 wherein the bed pan has a central longitudinal axis; 
 wherein the bed pan includes end walls extending intermediate the front and rear walls; and 
 wherein the mattress support surface has a recess-free portion extending laterally from the central longitudinal axis to the rear wall and extending longitudinally between the end walls. 
 
     
     
         9 . The wall bunk of  claim 1  wherein the front wall has a rail mounting portion with a rail length extending parallel to the length of the body and a cross-section perpendicular to the rail length that is uniform for a majority of the rail length to permit the rail to be connected to the rail mounting portion and slid therealong. 
     
     
         10 . The wall bunk of  claim 1  wherein the rail and front wall of the bed pan are configured to form a slide connection therebetween that permits the rail to slide along the front wall. 
     
     
         11 . The wall bunk of  claim 1  wherein the mounting portion has six or fewer openings for receiving anchors to secure the wall bunk to a wall. 
     
     
         12 . The wall bunk of  claim 1  wherein the body is rotationally molded high-impact polyethylene. 
     
     
         13 . The wall bunk of  claim 1  wherein the body has an interior that contains air. 
     
     
         14 . The wall bunk of  claim 1  wherein the body has an interior that contains structural foam.
